So your connecting the xbox, ps3, dvd player, to the HDMI port on the right side of the chassis? Those devices have to be set to send the HDMI audio into the M17x-R3. Have you check their audio menus? Have you then opened the IDT92HD73C audio control panel and checked the Playback settings?

Basically I'm referring to connecting my PS3 to my R3. The settings are all set to HDMI as it is usually set up with the TV via the same setup so there shouldn't be any issues there with audio settings.

I have a Nvidia GTX 460M, Im not to sure if there is ment to be any audio options there, I have searched around my laptop for all my audio controls and all I can find is the basic Audio setup on the start bar icons by time & date.

The only settings in there are HDMI out (Sony TV), 2 speaker settings (3.5mm jack) and a S/PDIF input.

Is it a possibility I am missing some software or a driver to run/ control the HDMI Input sound? Thats the only conclusion I can think of.

I dont have those software features on my R3 unfortunately. I have however temporarily solved this problem by using an eternal sound source in the means of px5 wireless headset. And I dont plan on using it as a monitor to much more in the future. Thanks for the reply's everyone

I know this is an old thread and I am slightly behind. WHen I open my Sound Blaster Recon3Di Software and go the mixer page. The last line in the line of HDMI input as a small square with the setting symbol on it. I can not seem to find the listen to this device button.
